How to add a Panel Help in a Plugin in Rhino 7

When some Rhino commands are executed, then a panel like this image appears

I would like to add a panel like this in my plugin.

How can I do it?


Your command should override the protected property CommandContextHelpUrl. This is usually a location of a local CHM file, but you can also provide an online URL with help for your command.

Thank you very much for your attention.

I’m going to implement your suggestion.

Thanks to the answer of a member of this forum I managed to display a website in Panel Help.

Now I’m trying to automatically open the Panel Help with a website.

To implement this I have added the following code:

var panelId = Rhino.UI.PanelIds.ContextHelp;

With these lines, the Context Panel Help opens, but the website is not displayed.
However, when Panel Help is opened and I run the plugin, the website is displayed.

Probably I need to update the Panel Help after opening but I do not know which command I can use.


I think this is the way it is supposed to work, the Help panel shows the help for the command that is being executed - try it with normal Rhino commands.

Thanks for your help. What do you mean when you say “try it with normal Rhino commands”?

I am thinking to create a special panel to show my help.


What I’m trying to say is that if you have the help panel open, and try a few rhino commands, you’ll see the help panel updating itself each time a new command is started. It seemed that you were expecting it to open directly on your help page when you programmatically open the help panel, at least that is what I understood from your post. You’ll also have to start a command for your plug-in to show its help though.
